INTERCHANGEABLE DIE FOR THE MANUFACTURE OF JEWELRY.

SPECIFICATION forming part of Letters Patent No. 443,383, dated December 23, 1890.

' Application filed March 6, 1890- Serial No. 342,885. (No model.)

To aZZ whom it may concern.-

Be itknown that I, HENRY B. VEIT, of New York, in the county and State of New York, have invented a new and useful Interchangeable Die for the Manufacture of Jewelry, of which the following is a full, clear, and exact description.

This invention relates to an improvement in dies for the production of ornamental designs upon plates of metal used in the manufacture of jewelry of various styles and kinds.

Heretofore in the formation of designs upon sheet gold or silver, which is the initial step in the manufacture of some kinds of jewelry, engraved dies have been employed, upon the surface of which the material to be ornamented by embossing or intaglio work is placed and held, the die and superimposed strips of metal being passed through between a pair of true rollers, which process forces the sheet metal into such intimate contact with the engraved or raised surface of the die as to produce an exact counterpart of the design on the soft strip of metal.

There are large numbers of dies needed by a manufacturing jeweler to furnish the various designs required in the several lines of special product manufactured by die process, and each die has to be rendered parallel on its sides and engraved withits special design. The steel used in die formation must be of the best quality and a considerable mass and weight are required in the production of each die. Consequently the outfit of a factory in the matter of dies involvesaconsiderable expenditure of money.

The object of this invention is to provide an interchangeable die or combination of diestock and separate dies, which may be assembled in the stock and afford different designs by use of a variety of small dies that are light and comparatively inexpensive, the composite die when completed by the assembling of a suitable number of die-sections being equally as efficient in service as a solid die when used to impress intaglio or relief designs upon strips of metal by passing theimposed sheet metal and composite die between rollers.

To this end my invention consists in certain features of construction and combinations of parts, as is hereinafter described, and indicated in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all of the figures.

Figure 1 is a perspective view of a the stock and interchangeable dies clamped th erein. Fig. 2 is an end view of the die'stock and dies therein. Fig. 3 is a transverse section of the die-stock with dies removed. Fig. 4 isa view of one die removed from the stock, and Fig. 5 represents a plan view of the complete device.

The die-stock A is formed rectangular of steel preferably, the dimensions being suitable for the style of work to be executed.

Through the transverse center of the block from which the stock A is made a longitudinal channel a (see Fig. 3) is formed, leaving parallel walls I) standing, which are held integral by the material belowthe channel, thus affording a stock wherein several small steel dies 0 may be placed in series, the bodies of said dies being formed to fit closely against the vertical walls I) and joint truly with each other. The heightof the dies 0 should be proportioned to the depth of the channel a, so that their upper end surfaces will conform with the face of the die-stock when a proper number of dies are placed and secured in the die-stock.

At each end of the stockAclamping-plates B are secured by the screw-bolts d, which are inserted in tapped holes that are formed in the ends of the walls I), said plates conforming in shape and dimensions to the ends of the stock. A, and are of such thickness as will render them substantial, steel or other suitable metal being employed for construction of the clamping-plates and screw-bolts.

If a pattern is desired which is elongated, such as an opened wreath, the proper length of stock being provided and dies clamped therein, the artist produces the complete design on the assembled dies, each of which receives its appropriate portion of the wreath, which when finished is ready for use after the dies are separately hardened and polished on their working-faces.

It is apparent that each die may be imsettes, stars, clover-leaves, and letters of the Patent alphabet, if desired, which characters can be The combination, with a steel stock which impressed or raised in relief, as may be preis longitudinally channeled throughout its 20 terred, and when these are assembled a strip 3 length, forming two parallel integral walls, of metal can he impressed or embossed with I and a series of (lies independently engraved a series of varying designs or letters to form or embossed to form ditl'crcnt combinations rings, lace-pins, and other articles ofjewelry, in the stock, of clamping-plates and screwthe same diestock answering for the retenbolts that are secured to the ends of the die- 25 10 tion in proper condition for use of dilferent stock and hold the dies in place on the stock,
